Superconducting fault current limiters

IEE Colloquium on High Tc Superconducting Materials as `Magnets', 1995
Fault current limiters (FCLs), superconducting or otherwise, have the potential to reduce fault levels on electricity power networks, and may ultimately lead to lower rated components (i.e. cheaper) being used, or to increased capacity on existing systems.

Design Consideration of a Dual-Functional Bridge-Type Fault Current Limiter

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020
To sufficiently utilize a bridge-type fault current limiter (BTFCL) in the distribution grids, this article proposes a dual-functional BTFCL (DF-BTFCL), which can work either at the BTFCL mode to limit faulty currents or at the dynamic voltage restorer ...

A superconducting fault-current limiter

Journal of Applied Physics, 1978
A conceptual design is presented for a fault-current limiter for the electrical power utilities which utilizes a superconducting element to commutate the fault current into a shunt resistor. The technical feasibility of the concept is supported by a computer simulation of the switching.

Cognition on the current-limiting effect of saturated-core superconducting fault current limiter

2015 IEEE Magnetics Conference (INTERMAG), 2015
The saturated-core superconducting fault current limiter (SCSFCL) is an important facility for limiting the short-circuit fault current of the power grid. However, the cognition or the judgment on the current-limiting effect, which is the key indicator of the SCSFCL, is not unique.
